SOD-CUTTING ATTACHM ENTCFOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 664,254, dated December18, 1900.

Appnuamn inea August 25,1900, saranno. 27.967. (No model.)

T0 all whom, it may concern:

Be it known that 1, FREDERICK GARDNER, a citizen of the United States,residing at Thornton, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Sod-Cutting Attachmentsfor Plows; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to a sod or earth cutting attachment for plows,and has for its object to provide a device of this characterV that maybe adjustably secured to the opposite side of the share from thelandside.

In the accompanying drawings, Figure l is an elevation in perspective ofa moldboard and plowshare, showing the relative position of theattachment, the plow frame being broken away. Fig. 2 is a side elevationof the cutting attachment, the portion of the share shown in this gurebeing in part section; and Fig. 3 is a horizontal section on line 3,Fig. 2, looking in the direction in'dicated by the arrow.

A may represent a moldboard, B a plowshare, and C the sod-cutting blade.The cutting-blade, as shown, is placed in a vertical position on theopposite side of the share from that of the usual colter or cuttersupported from the plow-beam and may be used jointly therewith orindependently, as circumstances may require. The lower end of the cutteris provided adjacent to the front cutting edge with adownwardly-projecting attaching-bolt a, terminating in the horizontalhook end d. The share is provided with one or more apertures c2 for theinsertion of the hook-bolt ct from the upper side. The lower end of thecutting-blade is provided. at the back side with a downwardly-projectingAclamping-bolt b, which is adapted to engage with the back edge of theshare, as at b'. The lower p0rtion of this bolt is threaded for theengagement of the clamping-nut h2. Plowshares are of different forms,and when itis not convenient to clamp on the back edge holes may beprovided in the share for the engagement of the bolt b. A number ofapertures may be provided, so that the cutter can be set nearer orfarther away from the landside in accordance with the width of the pathor furrowslice to be cut.

The base of the cutter is provided on opposite sides with companion lugsd, which are adapted to have a bearing on the surface of the share andguard against a lateral strain in holding the cutter in its uprightworking position.

The cutter gradually narrows from the base to the top and presents aninclined backwardly-cnrved cutting edge D and provides for a shearingcut, so that the sod and-roots are more easily cut than if the bladepresented a straight instead of a curved cutting edge.

The cutter or blade is placed in position by first tipping the sameforward and then inserting the attaching-bolt c. Then tip the bladeback, which brings the hook a to a retainingbearing against the underside of the share and at the same time bringsv the clampingbolt b intoits engaging position for the reception of its clamping-nut. By thismeans the cutting-blade is iirmly mounted on the share in its workingposition. This arrangement provides means for cutting the sod on bothsides of the furrow when used in connection with the ordinarybeam-colter or sodcutter.

I claim- 1. In a plow, the combination with a share, of a cutting-blade,mounted on the opposite side thereof from the landside, substantially asdescribed.

2. In a plow, the combination with a share, provided with one or moreapertures, of a cutting-blade, having a backwardly-curved cutting edgeand adjustably mounted on the furrow side of said share, substantiallyas described.

, 8. In a plow,the combination with a share, of a sod or earth cuttinglblade, mounted on the furrow side thereof, and means for securing saidblade in its working position, substantially as described.

4. In a plow, the combination with a share, of a cutting-blade, providedon the lower end with attaching-bolts and companion bearinglugs, andadapted to be mounted on the furrow side of said share, substantially asdescribed.

In testimony whereof I aflix my signature in presence of two witnesses.

FREDERICK GARDNER.
